记录不常使用且碰到又找不到的命令以及碰到的问题和解决方案。本文会持续更新…

一条命令实现安装VM-tools

sudo apt install open-vm-tools-desktop

说明：此为开源的软件包，非VMware自家的

Linux挂载samba

mount -t cifs -o vers=3.0 //192.168.216.155/share /opt/

ubuntu22.04 php7.x编译时依赖openssl报错

错误如下

expected ‘RSA *’ {aka ‘struct rsa_st *’} but argument is of type ‘const struct rsa_st *’ 289 | RSA *rsa, int padding);

解决方案：https://github.com/phpbrew/phpbrew/issues/1263

export PKG_CONFIG_PATH=PATH/TO/OPENSSL/bin/lib/pkgconfig

Docker查看镜像制作过程

# 从下到上的过程
docker history --format {{.CreatedBy}} --no-trunc=true {IMAGE_NAME}

# 反过来
docker history --format {{.CreatedBy}} --no-trunc=true {IMAGE_NAME} | sed "s/\/bin\/sh\ -c\ \#(nop)\ //g"|sed "s/\/bin\/sh\ -c/RUN/g" | tac

记一次istio部署完成后，无法注入成功

# 修改kube-apiserver的配置
vim /etc/kubernetes/manifests/kube-apiserver.yaml

# 加一条启动参数
--enable-aggregator-routing=true

一条命令在Kubernetes中创建一个Debug Pod

kubectl run -i --tty --rm debug --image=busybox --restart=Never -- sh

也可以指定自己制作的镜像

使AWS EC2创建时无需密钥连接（测试使用）

#!/bin/bash
# 设置允许密码认证
sed -i "s/#PasswordAuthentication no/PasswordAuthentication yes/g" /etc/ssh/sshd_config

# 修改端口
echo "Port 2314" >> /etc/ssh/sshd_config
systemctl restart sshd


# 添加新用户，并给用户设置密码以及sudo权限
useradd jadmin
echo "jadmin:j0e*Njebp.u^#j@#]6-J^RCM?:h,d-"  | sudo chpasswd
sed -i "s/ec2-user/jadmin/g" /etc/sudoers.d/90-cloud-init-users

获取QuickStart中的AMI(python request)

def find_quickstart_ami():
    url = "https://prod.us-west-2.qs.console.ec2.aws.dev/get_quickstart_list_zh.json"
    res = requests.get(url)
    quickstart_ami_json = res.json()

    for ami in quickstart_ami_json["amiList"]:
        # 判断是否是mac操作系统
        if ami["platform"] == "x86_64_mac":
            continue

        # 判断是否为免费镜像
        if not ami["freeTier"]:
            continue

        if len(ami["architectures"]) == 0:
            print(f'title: {ami["title"]} | imageId:{ami["imageId64"]}')
        else:
            print(f'title: {ami["title"]} | imageId: {ami["architectures"][0]["imageId"]}')

AWS镜像AMI(ImageId)

AWS CLI连接EC2

aws ec2-instance-connect ssh  --instance-ip 34.214.171.61 --region us-west-2  --instance-id i-0b8da26f77303ebb9 --os-user centos --connection-type direct --ssh-port 22

有时无法连接，请忍受
